Job Description

Company Description

ModernPixel is a software development agency dedicated to creating scalable, user-focused digital solutions for businesses and startups. We specialize in developing elegant frontends, robust backends, and high-performance products that prioritize quality and impact. Our services include web and mobile app development, custom software, and UI/UX design. With a team of innovative professionals, we deliver clean code, reliable architecture, and efficient iterations to bring ideas to life.


Role Description

This is a contract remote role for a Senior Backend Developer. We’re looking for a Senior Backend Developer who can own backend architecture, build reliable APIs, and ensure our systems scale smoothly. If you’re strong with Node.js, PostgreSQL, and AWS services, you’ll feel right at home.


Key Responsibilities

  • Design, build, and maintain scalable backend services using

    Node.js

    (Express/Nest/Fastify).
  • Architect clean and efficient REST or GraphQL APIs with proper versioning and documentation.
  • Work extensively with

    PostgreSQL

    — schema design, indexing, query optimization, migrations.
  • Implement caching, rate-limiting, background jobs, queues, and event-driven workflows.
  • Manage deployments and infrastructure on

    AWS

    (EC2, ECS/Lambda, RDS, S3, CloudWatch, IAM).
  • Ensure strong security practices: auth, permissions, encryption, and data protection.
  • Optimize service performance, reliability, and error monitoring.
  • Collaborate closely with frontend, product, and QA to deliver end-to-end features.
  • Conduct code reviews and contribute to backend engineering standards.

Required Skills

  • 4–7+ years of backend development experience.
  • Expert-level proficiency in

    Node.js

    , TypeScript, and modern backend frameworks.
  • Strong command over

    PostgreSQL

    — complex queries, joins, triggers, indexing, performance tuning.
  • Deep understanding of AWS fundamentals — networking, IAM roles, logging, deployments.
  • Experience working with ORMs (Prisma/TypeORM/Sequelize) or raw SQL.
  • Familiarity with Docker and CI/CD pipelines.
  • Solid understanding of distributed systems and API reliability patterns.
  • Strong debugging skills with observability tools (CloudWatch, Sentry, Datadog, etc.).

Good to Have

  • Experience with microservices or monorepo architectures.
  • Knowledge of Redis, RabbitMQ, SQS, or Kafka.
  • Experience implementing automated tests (Jest, Supertest, Playwright for API).
  • Exposure to infra-as-code (Terraform/CloudFormation).
  • Understanding of security frameworks (OWASP, JWT, OAuth2).

What We’re Looking For

  • Someone who can think in terms of systems and architecture, not just endpoints.
  • Someone comfortable handling scale, performance issues, and production-grade deployments.
  • Someone who can take ownership, communicate clearly, and mentor others.
  • Someone who enjoys solving problems and building reliable backend foundations.
